I wonder if this is related to memory pinning. Can you try turning off
the leave pinned, and see if the problem persists (this may affect
performance, but should avoid the crash):
mpirun ... --mca mpi_leave_pinned 0 ...
Also it looks like Smoky has a slightly newer version of the 1.4
branch
Hello,
Thank for the answer.
I am testing with OpenMPI-1.4.3: my computation is queuing. But I did
not read anything obvious related to my issue. Have you read something
which could solve it?
I am going to submit my computation with --mca mpi_leave_pinned 0, but
do you have any idea how it
One possibility: if you increase the number of processes in the job, and they
all interconnect, then the IB interface can (I believe) run out of memory at
some point. IIRC, the answer was to reduce the size of the QPs so that you
could support a larger number of them.
You should find info
I'm having some issues with MPI_File_seek_shared. Consider the following
small test C++ program
#include
#include
#define PATH "simdata.bin"
using namespace std;
int ThisTask;
int main(int argc, char *argv[])
{
MPI_Init(,); /* Initialize MPI */
MPI_Comm_rank(MPI_COMM_WORLD,);
MPI_File
Hi,
Thanks for your answer. It makes sense.
Sorry if my question seems silly, but what does QP mean? It is difficult
to read the FAQ without knowing that!
Thanks.

Hi,
What happens when you don't run with per-peer queue pairs? Try:
-mca btl_openib_receive_queues S,4096,128:S,12288,128:S,65536,128

Hi,
QP = Queue Pair
Here are a couple of nice FAQ entries that I find useful.

Dear all,
Thanks a lot for your support. I only had time to test one today, but it
seems the option --mca mpi_leave_pinned 0 works on my case. I will go
further next week, but for the moment, I can submit my computation.
Thanks a lot for your help.
